IThis invention relates to adzing machines and particularly machines ofthe type employed in gaining railway ties to provide seats for thereception of the rail plates. More particularly the invention relates toan adzing machine having an arrangement for adjusting the depth of thecut actuableduring the operation of the machine.

The present invention comprises`n an improvement upon the type of adzingmachines already known wherein a mechanism is provided for automaticallydetermining, in accordance with'the irregularities in the shapes of theties, the depths of the cuts to be made, whereby all of the cuts are ofsubstantially uniform depth irrespective of the irregularities in theshape of each tie. In prior art devices of this type, no satisfactorymechanism actuable during the operation of the machine and independentlyof the automatically operating mechanism, has been devised for adjustingthe depth of the cuts.V

ere ties of varying degrees of roughness are to be gained, it isdesirable that the machine be adjusted to make a cut in accordance withthe nature of the tie whereby, if a tie having a relatively smoothsurface is to be gained, a cut of minimum depth may be made, whereaswhen a tie having a rough surface is to be gained, a cut may be made ofsuch depth that a` smooth surface will be produced. According to thepresent invention, a mechanism is provided which is operable during theworking of the machine to adjustl the depth of the cut independently ofthe operation of the automatic means.

An object of the present invention is to provide an adzing machine ofthe above stated type in which the depth of the cut may be adjustedduring the operation of the machine.

Another object of the invention is to provide in an adzing machine ofthe type wherein the depth of the `cut is regulated automatically inaccordance with the irregularijects will ties in the shapes of the ties,a mechanism for manually adjusting the machine to make a cut ofpredetermined depth. Other obappear from the following descrip- SerialNo. 581,452.

tion taken with the appended drawings,

lgs. 2 9 are detailed kviews of several mod-A ified forms of theadjusting mechanism, and Fig. is a view showing a mechanism for liftingthe ties independently of the cradles. Inasmuch as the machine issubstantially symmetrical about a centrally passed plane, and the twohalves are therefore enantio- Inorphic, the following description willbe limited to one half of the machine except as to those elements-whichare not similar in both halves. y Referring to the right-hand half ofFig. 1, a base 1 supports a frame 2 on which is rotatably mounted anadzing cutter 3 which is driven by a pulley 4 connected to a suitablesource of power (not shown). Encompassing the upperportion ofthe cutter3 is a cradle 5 comprising a pair of side rails 6 and a pair of Y-shapedendrmembers 7, each of the latter being carried on a verticallyreciprocable pivotl pin 8, whereby the cradle is tiltable and verticallyreciprocable. The depending portion 9 of each end member is slotted forhinging cooperation with the reduced end 10 of a thrust member 11 whichis carried on a vertically reciprocable pivot pin 12. The lower endofthe thrust member 11 is provided with a head 13 having a toothed arcuatelower edge 14, the curvature being such that the distance is greaterfrom thev pivot pin 12 to vthe teeth at the center than it is to theteeth at the end portions. Y

Disposed somewhat below the head 13 is a wedge-like member 15 havingajhorizontal toothed upper edge 16 and an inclined lower edge 17 of thewedge member 15 to lift the c same into engagement with the head 13 whenplurality of cam blocks 24 adapted to bear e into engagement with thecutter 3'.

against a cam rail 25 scured to the adjacent end of the crank 19 to urgethe upper end of the crank 19 in a counter-clockwise direction.

The endless chain 22 also carries a plurality of properly spacedabutments 26 which serve to transport the ties tobe gained past .f thecutter 3, rail 27 being disposed above the upper lap of the chain 22`toprovide a riding surface for the ties. Disposed above each cradle 5 is aresiliently mounted roller 28 which serves to maintain the correspondingend of a tie 29 in contact with the cradle 5.

A thrust member and crank similar to those seen in Fig' 1 are providedat the rear of the frame member 2 and cooperate with a second Y-shapedmember and the near end of the cam rail respectively, in a similarmanner.

Referring to the left-hand half of Fig. 1, a wedge member 30 is disposedsimilarly to the first wedge member but has its lower edge inclined inthe same direction. The two forward wedge members 15 and 30 areconnected by the connecting member 18 and two similar wedge members (notshown) which cooperate with the rear pushers and cranks (not shown) areconnected by a second connecting member 31 which is also guided in theframe 2 for horizontal and vertical movement, The connecting members f18 and 31 are connected by a linkage mechanism 32 to an operating lever33 by means of which the connecting members 18 and 31 may bereciprocated in a horizontal direction to move the wedges 15 and 30 intoand out of the space between the heads 13 and the bearing members 20.The lever 33 and consequently the wedge members 15 and 30 are maintainedin any one of several positions by a holding mechanism 34 of known type.

The operation of the machine is as follows (considering` only theright-hand portion of the machine) A tie is fed onto the rails 27 and ispushed there'along by the abutments 26 until it reaches the cradle 5onto which it rides, being held firmly thereon by the rollers 28 bearingagainst its top surface.

If the tie is not irregular in shape the cradle 5 remains leveland thetie iscarried Just rior to the engagement between the cutter and thetie, the cam block 24: rides onto the cam rail and presses the sameoutwardly to rock the crank 19 in a counter-clockwise direction. Thebearing member 20 lifts the wedge 15 into engagement with the head 13and the cradle 5 is thereby lifted to raise the tie a predetermineddistance. Since the pusher member 11 is in a vertical position, thedistance between the pivot 12 and the portion of the head in contactwith the wedge is a maximum and the cradle is therefore raised a maximumdistance and hence, a cut of minimum depth is made.

1f the tie is irregular in shape, the cradle 5 is tilted and, throughthe agency of the depending portion of the Y- haped member 7 and thepusher member 11, a corresponding lateral displacement is imparted tothe head 13. In such a case, when the crank 19 is rotated to raise thecradle 5, the distance the cradle is raised is less than the maximumdistance because of the fact that the distance from that portion of thehead 13 engaged by the wedge member 15 is less than the maximum. Thus,it will be seen that a deep cut is made in the tie and further it willbe seen that, since the curvature of the toothed head 13 varies frommaximum to minimum, the extent the cradle is lifted is dependent uponthe degree of tilting of the cradle which, of course, is determined bythe extent of irregularity in the shape of the tie.

lWhere the tie is relativelyV smooth and it is thus desirable to takeonly a shallow out, the handle 33 is operated to move the wedge members15, to the left as viewed in Fig. 1. The effective thickness of thewedges is thus increased and consequently the cradles are raised agreater distance than when the wedges are in the positions shown inFig. 1. Where the tie is relatively rough and it is desirable to take adeep cut, the wedges are moved into the positions shown in Fig. 1.

` This arrangement for adj ustingthe extent of elevation of the cradlesis operable during the operation of the machine, since only a simplemovement of the lever is required to make the adjustment. The adjustmentmay be made between the engagement of the cutter with two successiveties. It will now be apparent that an operator may be stationed at themachine and, upon observing thek motive of each tie, may adjust thelifting arrangement for the most suitable lift whereby a cut of optimumdepth for that particular type of tie may be made.

It will be seen from the foregoingithat the operation of the adjustingmechanism in no way interferes with the automatic adjustment of thelifting arrangement in accordance with the irregularities in the ties.rIhe manual adjustment may be made whether the automatic adjustmentprovides for a deep or shallow cut. f Y

Vwedge member a This form operates in If it is desired that no cut shallbe made in a tie, the lifting mechanism is adjusted to lift the cradlessuiiciently to raise the tie entirely out of contact with the cutters.

In Fig. 2 is shown a modified form of wherein there is provided, insteadof the inclined lower edge 17, shown in Fig. 1, a stepped lower edge 17awhich cooperates with the bearing member a. substantially the samemanner as the first form, the wedge member 15a being moved with respectto the bearing member 20a to vary the height of the toothed up'per edge16a with respect to the bearing member 20a. Y

Fig. 3 illustrates another form wherein the wedge member 15 is providedwith a horizontallower edge 17b resting on the crank 19b and an inclinedupper edge 16 cooperating with the bearing member 2()b to raise or lowerthe same with respect to the crank 19b as the wedge member 15b is movedhorizontally. Instead of the wedge member 15b, shown in Fig. 3, a member15c having a horizontal lower edge 17 c and a stepped upper edge 16c maybe provided, as shown in Fig. 4.

somewhat dierent arrangement is shown in Fig. 5, wherein there is noadjusting A member cooperating with the bearing memlll 1 rotated inplaceable ries the bearing` ber 20Ti but a wedge member 35 actuated by acrank 36 pivoted to the end of the` main crank 19d determines theposition of the cam rail d which in this form, is movable on the crank19d. W'hen the 'adjusting crank 36 is a counter-clockwise direction, itmoves the wedge member upwardly to force the cam rail 25d away from themain crank 19 and thus, when the cam block (not shown) bears against therail 25d the main crank 19d is rotated through a greater angle than whenthe wedge 35 is in the position shown.

In Fig.

6, the pivot pin 37 which carries the crank 19e is mounted in ahorizontally disbearing 38 mounted in an eccentric 39, which eccentric39 is provided with a lever 40 for rotating the same. If the lever 4()is rotated in a clockwise direction, the bearing 38 is moved to theright as viewed in Fig. 6) and the upper end of the crank 19V` whichcooperates with the cam block (not shown) is displaced to the right.This displacement causes the arm which carmember 20e to be displaced agreater distance by the passage of the cam block than when the crank 19eis positioned as shown in Fig. 6.

Fig. 7 illustrates still another form of adjusting means. In this form ahead 40 is pivoted to the end of the arm of the crank 19f and carries aplurality of radially arranged bearing members 201' of graduatedlengths. The adjustment is made by rotating the head 40 to bring thatone of the bearing members 2Ot having the desired length of the crank19e of the cut. y This mechanism may be employed in place cradles tiesin into engagement with the head of the pusher member (not As shown inFig. 8, a cam-like head 41 may be provided instead of the head 40carrying the several bearin members 20f. form, the head 41 gearsdirectly against the head of the thrust member. The rotation of the head41 varies the distance between the crank arm 19i and the head (notshown) of the thrust member.

Fig. 9 shows diagrammatically an arrangement of levers for operating theembodiments of the adjusting member shown in Figs. 7 and 8. A pairoflevers 43 is pivoted to the heads 41 and 42 and pivotally connected attheir inner ends'to an armof a" crank 44, the other end of which isconnected by a connecting member 45 to a control lever 46. The movementof the control lever 46 is transmitted through the linkage to the heads41 and 42 which may be rotated thereby to the desired position. f

Thereyis illustrated in Fig. 10 a mecha- (not shown) shown) nism forlifting ties with respect tothe cutters. A frame 47 disposedabout thecutter is carried on swingable supporting members 4S which are pivotallyconnected to the frame 47 whereby the frame 47 may be raised or loweredby rotation of the supporting members 48 but will be maintained inhorizontal position at all times. are provided for moving the lframe 47.The frame 47 is arranged to support the ties as they are carried pastthe cutter 3j and may be raised or lowered of thecradle mechanism wherethe ties to'be gained are so uniform i irregularities Vneeds to be made.The arrangement may also be employed in-combination with the cradlemechanism to lift from the which only very shallow cuts need be made.

It should be obvious that the present inven-V tion is notflimited tomachines for gaining railroad ties but may be applied to any type ofwood working machine wherein vit is de-y 0 position of the work piecebe' adjusted with respect to the cutting mechasirable that the msm.
